Abstract
BackgroundInfected non-union of long bones is a problem in the developing countries. Persistent infection, deformity, shortening, bone loss, joint stiffness and disability complicate the non-union. Secondary procedures are often required for correction of bone defects and deformity. Ilizarov method addresses all the above problems simultaneously and offers a panacea for infected non-unions. The stability of the fixation and provision for bone transport allows bridging of bone defects, limb lengthening, early weight bearing ambulation and joint mobilisation.Aim of the studyTo know the suitability of this procedure in recalcitrant infected tibial non-unions in the Indian population and the influence of socio-economic factors in the functional outcome.Method of studyThis was a 3-year prospective study in 22 consecutive patients with an average follow up of 13 months following fracture union. The results were analysed using the ASAMI scoring system.ResultsOf 22 patients in the study, 13 patients who underwent external bone transport, had an average bone gap of 4 cms [2–11 cms] with an average duration of fixation of 9.3 months [6.5–13 months]. There were 4 excellent, 3 good, 4 fair and 2 poor bony results and 1 excellent, 3 good, 6 fair and 2 poor results. 1 patient was lost for follow up at final functional analysis. 9 patients who underwent internal bone transport had an average bone gap of 5.4 cms [1.5–9 cms] with an average duration of fixation of 8.5 months [4–11 months]. There were 3 good 4 fair and 2 poor bony results and 1 good, 3 fair, and 2 poor functional results. Good to excellent results were witnessed in well-motivated patients with adequate social and financial support. Patients with fair to poor results preferred amputation to limb salvage despite the fact that they retained their limbs.ConclusionTreatment of infected non-unions of Tibia with Ilizarov ring fixation is effective but for optimal results the treatment needs to be individualised by the treating surgeon with due consideration of the socio-economic factors.

Summary
Infected non-union of long bones is a problem in the developing countries. Persistent infection, deformity, shortening, bone loss, joint stiffness and disability complicate the non-union. The stability of the fixation and provision for bone transport allows bridging of bone defects, limb lengthening, early weight bearing ambulation and joint mobilisation. Secondary procedures are often required for correction of bone defects and deformity. This eventually results in multiple surgeries and scarring of the tissues with joint stiffness and oedema, which interfere with an optimal limb function. The stability of the fixation allows weight bearing ambulation and joint mobilisation. Infection control is achieved by radical debridement of the infected tissues including bone and followed by bone transport to reconstruct the residual bone defects
